Hi All,
I just finished installing my infinity this evening. I have the science of speed kit. I was wondering if anyone has a good tune that I could use as a starting point in lieu of the AEM base tune.

 

SOS is a good starting point, but I also have a few recommendations. Like check all of the inputs, outputs (VTEC). Configure TPS sensor.

Also, is knock sensor enabled and partially-configured? How about AIT & Coolant, sometimes they don’t seem to be auto-selected even with PNP system.

Now, how about your VE2 (VTEC) map. Also did you disable VEtable2 (so VTEC) so you can limp to the tuner on the low cam? Make sure your injector characterization is in check.

Also be sure to cross reference the ignition timing at idle, say at 5 or 0 degrees mark, using a timing light. Don’t trust the preset 10.5 offset which is what AEM/SOS configured as some are off by 2-4+ degrees from that.

So, overall I know the tune you’re talking about, SOS base one. It should get you to your tuner safely especially if you dial IN your AFR and dial DOWN your ignition (spark).

Edit: please don’t tell me you’re doing analog wideband. Please do tell me it’s onboard or CAN (x-series).

 

Im using the wideband provided with the kit, that is wired into the infinity.

I havent fired up the ECU yet, just got done installing and wiring when I had to go cook dinner, darn adulting...

I would like to get a tune from someone that is running it successfully so that I dont have to limp to a tuner... still going to one on Saturday anyway

 

If you've ever tuned a car before it's fairly easy. I use a different brand for my Porsche but this was fairly easy to pick up and there are many tutorials on the internet.

 

^ this man knows...take full advantage of the AEM but do doublecheck the calibration...
The SOS printed manual is a good place to start

ideally I would flatbed the car to the tuner so that someone with some expertise can help getting the initial dial in correct

 

You have an SOS base tune, pretty reputable if you ask me. Sounds like you just want to click and go, well, you have that now. You don’t have to take the precautions I’ve recommended.

 

Thats not it at all, I was just hoping to spend less time with the tuner this weekend. Thank you for all your input, I plan on checking all those things, I am currently waiting for the thread sealant on the fuel pressure sensor to cure before firing up the ignition and the ECU for the first time.

 

Ah, yes yes, fuel, smart.

I understand but most tuners will still charge you a flat fee at the end of day. They want it their way, their tune, their settings, their tables and layout. Can’t blame them tbh because then it’s theirs, they might password lock it and if not at least recognize the options and track down any issues quicker if any arise.

Anyways, how long is the drive to your tuner? What’s your setup (SC or Turbo) and do you have access to a cheap, basic, timing light?

 

18mi/30mins

Its an NA car, completely stripped and setup for ST4/TT4. I wanted more control over VTEC engagement and engine added protections, had my original F20 go bang last year. I also wanted some future proofing because I would like to add an SC down the road or if this motor goes I am also building a K24 in the background that I can put in.

Yes, I do have a timing light

 

since its likely close to stock N/A, you'll probably be fine using the downloadable AEM basemap through the AEM portal once you register your ecu...just keep a light foot on your drive to the tuner, and have a way to watch your AFR as you drive, and verify the timing before starting it up. You'll also need a coil plug jumper for the inductive pickup on your timing light.

have fun!
